说明：  这是自由空间路径损耗的代码。里面有多个m文件(This is the code of path loss in free space. There are multiple M files in it.)

界面使用C#开发，底层使用C++开发的无线电脑锁软件。采用蓝牙通信协议控制。(Interface using C# development, the underlying wireless computer lock software use C++ developed. Bluetooth communication protocol control.)

说明：  3. 瑞利信道中的调制解调、信道估计： (1) 请推导出单径瑞利信道中的BPSK相干解调的理论误码率性能，并画出比特信噪比与误码率的关系曲线。 (2) 在单径瑞利信道中，请设计一种时分的导引辅助的信道估计方法，用Simulink进行仿真，测量BPSK的误码率性能，画出比特信噪比与误码率的关系曲线，并与理论误码率曲线进行对比。(3. Modulation demodulation and channel estimation in Rayleigh channel: (1) deduce the theoretical bit error rate performance of BPSK coherent demodulation in single-path Rayleigh channel, and draw the relationship curve between bit signal-to-noise ratio and bit error rate. (2) in single-path Rayleigh channel, please design a time-division guidance assisted channel estimation method, Simulink simulation, measure the bit error rate performance of BPSK, draw the relationship curve between bit SNR and bit error rate, and compare with the theoretical bit error rate curve.)

在VC++6.0中用MSComm控件编程，可以实现串口接(used in VC 6.0 MSComm programming, serial port access can be achieved)

VB6.0与变频器的RS485或Modbus通讯，控制变频器的参数设定，运行状态，运行频率，读当前状态，电流，电压，频率，故障等。支持远距离控制。(VB6.0 and drive the RS485 or Modbus communications, control the inverter parameter settings, operation status, operating frequency, read the current state, current, voltage, frequency, fault and so on. Support remote control.)

matlab实现的fft程序，可酌情作为参考(Matlab implementation of the FFT program, as appropriate, as a reference)
